Physical Research Laboratory: Sahoo’s PRL Team Reconciles Sodium Theory With Experimental Data

Researchers at the Physical Research Laboratory have performed calculations on sodium (Na) to resolve discrepancies between previous theoretical predictions and experimental data regarding hyperfine structure constants. Their work utilizes relativistic coupled-cluster theory, including triple excitations, to better understand electron correlation and its impact on the nuclear region of the atom.

New screening tool spots RNA-disrupting antibiotics for drug-resistant gram-negative bacteria

Researchers from Skoltech and other science centers in Russia have developed a reporter system—a tool for screening potential new antibiotics—that enables the selection of drug compounds disrupting RNA synthesis in gram-negative bacteria. Among others, these include multidrug-resistant Pseudomonas aeruginosa, a dangerous pathogen responsible for hospital-acquired infections that has already adapted to existing antibiotics.

The cortisol fix: How 150 minutes of weekly exercise resets your stress biology

A year-long clinical trial published in March 2026 found that 150 minutes of weekly aerobic exercise significantly reduced long-term cortisol levels in midlife adults The study, conducted by University of Pittsburgh and AdventHealth Research Institute, tracked 130 adults aged 26-58 over 12 months Chronically elevated cortisol is linked to heart disease, metabolic dysfunction, impaired memory…
